    <h1>Basic structural interfaces.</h1>

<p>
  This package 
  contains interfaces for the most general algebraic structures used in JAS,
  e.g. <code>RingElem</code> and <code>RingFactory</code>.
  Some classes implement e.g. quotient rings or residue class rings, 
  based only on the interfaces in this package.
  The <code>Product</code> class implements a finite product of other ring elements.
